[Networker] NW 8 breaks yum

Hi guys,

After installing NW 8 on a PUIAS(essentially RHEL) 6.3 x86_64, following the 
installation guide, yum doesn't work anymore:



[root@dkarhnwsup ~]# yum update
Plugin "refresh-packagekit" can't be imported
Loaded plugins: downloadonly
Traceback (most recent call last):
  File "/usr/bin/yum", line 29, in <module>
    yummain.user_main(sys.argv[1:], exit_code=True)
  File "/usr/share/yum-cli/yummain.py", line 285, in user_main
    errcode = main(args)
  File "/usr/share/yum-cli/yummain.py", line 136, in main
    result, resultmsgs = base.doCommands()
  File "/usr/share/yum-cli/cli.py", line 434, in doCommands
    self._getTs(needTsRemove)
  File "/usr/lib/python2.6/site-packages/yum/depsolve.py", line 99, in _getTs
    self._getTsInfo(remove_only)
  File "/usr/lib/python2.6/site-packages/yum/depsolve.py", line 110, in 
_getTsInfo
    pkgSack = self.pkgSack

  ... many files mentioned ...

  File "/usr/lib/python2.6/site-packages/yum/repoMDObject.py", line 140, in 
parse
    parser = iterparse(infile)
  File "/usr/lib/python2.6/site-packages/yum/misc.py", line 1169, in 
cElementTree_iterparse
    _cElementTree_import()
  File "/usr/lib/python2.6/site-packages/yum/misc.py", line 1164, in 
_cElementTree_import
    import cElementTree
ImportError: No module named cElementTree
[root@dkarhnwsup ~]#

NW packages:

[root@dkarhnwsup ~]# rpm -qa |grep lgto
lgtonode-8.0.0.1-1.x86_64
lgtoserv-8.0.0.1-1.x86_64
lgtoman-8.0.0.1-1.x86_64
lgtoclnt-8.0.0.1-1.x86_64
lgtonmc-8.0-1.i686
[root@dkarhnwsup ~]#

All I've been able to find suggests updating a package called 
python-elementstree, but I can't find it for any RHEL 6 or its derived distros.

If I remove the NW packages, yum works again.

Any ideas?
